PCBA Automatic Cleaning Machine Description 1:

One、 Overview of pure water systems

According to the user's technical requirements, water and other technical indicators to municipal tap water quality as the basis, designed and provided the RO reverse osmosis + MB mixed bed ultra-pure water system (individual cities need to provide water quality report). The ultra-pure water system in accordance with the composition of the function can be divided into three major components, namely the pretreatment system, RO reverse osmosis system, MB mixed bed system;

Pretreatment system: By the multi-media filter (quartz sand, coconut shell activated carbon composition), cationic softener, pp cotton core fine filter composition; Its role is to remove the impurities in raw water, organic matter, residual chlorine, etc., to reduce the water SDI value, to prevent water in the calcium and magnesium ions in the reverse osmosis membrane scaling to protect the back-end process RO membrane system long-term stable operation. According to RO reverse osmosis water production requirements, pre-treatment standard water capacity is designed to 1m3 / h. RO reverse osmosis system: mainly by the high-pressure pump, reverse osmosis membrane, membrane pressure vessel components and other components. Play a pre-desalination effect on water. Raw water and salt content removal rate of 98% or more. Taking into account the natural aging of the reverse osmosis membrane with time, the allocation of margin, reverse osmosis standard water production of 250L / h, terminal MB mixed bed system water production of 0.5 tons / hour (room temperature) water production.

Water quality: RO reverse osmosis system desalination rate greater than 98%, terminal effluent resistivity reached 10 MΩ / CM for cleaning process water (25 ℃).

Raw water quality: local municipal water.

Two、Composition and operation of pure water system

1 Pre-processing system

Including multi-media filter (quartz sand, coconut shell activated carbon composition) PP cotton core fine filter.

1.1、Multi-media filter

1.11 The suspended matter in the water is smaller particles. The macromolecules are mainly composed of sediment, clay, protozoa, algae, bacteria, and macromolecules, and are often suspended in water. When the tap water through the quartz sand can remove the water in the large particles of suspended solids Activated carbon can remove water in the water creatures, plants or microbial breeding and decay and the smell of fish smell rotten smell of organic matter of corruption and decomposition of the smell of the soil or astringent smell , Disinfectant residual chlorine. To ensure the normal operation of the follow-up system. The reduction of chlorine in the water, the protection of softening resin and membrane components played a significant role in extending the reverse osmosis membrane and mixed bed life. The filler is granular shell activated carbon.

1.12 Flush multi-media filter: (Rinse cycle: 1-2 times per week, depending on local water quality)

Washing method:Multi-media filter manual control to the rinse position, rinse after 15 minutes to the positive position, and then rinse for 10 minutes, after the completion of the flushing, the multi-valve to the running state.

1.2、 Cationic softener

In order to prevent calcium in water, magnesium ions in the reverse osmosis membrane scaling, membrane components are damaged by solid particles, a large area of scaling.

Adding softeners before reverse osmosis of R.O can extend the system cleaning cycle and extend the membrane life to reduce costs. Flush regenerated cationic softener (cycle: depending on water quality) Methods as below:

(a) First in the industrial salt bucket, add 5 kg of industrial salt. And add water to dissolve 15 kg of saturated solution.

(b) Backwashing : The manual multi-way valve is dialed to the backwashing position (BACK WASH) for 15 minutes after dialing to the aspiration position (BRINE&SLOWR)

(c) Salt water :After the manual multi-way valve is dialed to the salt position (BRINE & SLOWR), it will automatically absorb brine (20-25 minutes).

(d) Fast rinse :After taking 20 kg of industrial salt solution, put the manual multi-way valve to the quick flush position (FAST RINSE) and rinse for 30 minutes.

(e) Sampling detection : Open the sample valve and remove the sample water. The requirements of the use of special softened water reagent inspection and inspection shall prevail.

Softened water sampling, dripping reagent, if the water color to blue as qualified, if the purple or red for the bad, to regeneration

Cleaning. After the completion of the normal water supply (SERVICE).

1.3、PP Fine filter

The safety filter is the last filter to enter the R.O reverse osmosis host, and it must ensure that the tap water enters the reverse osmosis

The host before the pollution index SDI stable below 4. As the reverse osmosis device pure water recovery rate is generally only 50% -60%.

Designed to produce water is 1t/h.

Principle of operation :

(a)PP cotton filter with 5um pore size of the PP cotton filter, water from the PP outside the penetration, through the pores from the PP cotton inner wall

Heart tube infiltration out, so as to filter out the pores than the larger particles of small particles.

(b)PP cotton after a period of time after use, the external hole trapping more and more impurity particles, until the failure, then be sure

Replace the filter, otherwise it will contaminate the subsequent reverse osmosis equipment, the general replacement cycle of 1-2 months (according to the local Water quality and water).

1.4 Precautions:

(a) Precise filter cartridge after use, the microporous traces of impurities will be more and more until failure. At this time, be sure to replace it in time. Generally change once a month, the replacement frequency with the original water quality and equipment use time may be, For the first time, it is possible to periodically check whether the filter is completely contaminated and need to be replaced every week. After several repetitions to determine the appropriate replacement cycle and continue.

(b)Check the SDI of the effluent from the safety filter on a daily basis. If the SDI value is greater than 4, check the filter inside the precision filter

Whether the core seal is damaged or loose, if the filter pollution, please replace the filter.

2 RO reverse osmosis system

2.1 Preface

RO reverse osmosis unit is the whole set of pure water system, the user should pay special attention in maintenance, usually in the RO system operation, the operation of the data obtained should be with the system design reference value to make appropriate adjustments. Adjustment to the membrane of the water and working pressure as the main indicators, combined with the membrane blockage and pollution of the situation to adjust. The water pressure, water pressure, water flow, water flow, pure water conductivity should be normal records, so that the system failure to identify the cause. In general, RO pure water system on the removal rate of organic matter can reach 99.9%. And for inorganic salts, up to 94% to 98%. As the RO system with high efficiency deionization of the fine ability, it can be the resistance of water, both by the system inle

And the outlet of the resistance to compare, come to its work efficiency. For the RO system in addition to the ability of minerals and organic matter due to periodic rinsing, drug washing operation, it can maintain a stable water quality. The following operational data are based on the following factors:

1)Water temperature is maintained within the design range (at room temperature around 25 ℃)

2)Water should be the same as the municipal water quality

3)Water must be pre-treated to reduce SDI and remove residual chlorine

The RO system uses automatic control technology, and has the necessary protection, such as water, water, low pressure protection, etc., but does not mean that the system can be long-term unattended operation, please regularly record pressure, flow, Conductivity parameters,When the system is designed to exceed the limits, please adjust the RO membrane or system, which will affect the life of the machine. It is recommended that users in strict accordance with the design specifications for operation and records, due to personnel operation errors and regulatory adverse,loss of the Company has the right not to take any responsibility.
